WebSocket tunnel endpoint. This module terminates the websocket tunnel from a client. This module then passes data (without websocket frames) to a backend and encodes responses from backend in websocket frames before sending responses to client.

EXPERIMENTAL (new in lighttpd 1.4.46)

Note: if looking to proxy websockets to a backend, then see Docs_ModProxy, Docs_ModCGI, or other backends, some of which can be enabled to be transparent proxies to backends after client sends Upgrade: websocket

Details for wstunnel.server parameters can be found in mod_fastcgi documentation, since the wstunnel module shares the same code infrastructure with the FastCGI module, and fastcgi.server parameters are very similar.
